Ceramic capacitors last longer

From the perspective of the life of the capacitor, the high-voltage ceramic capacitor has a longer service life. The life of film capacitors is three or two years, while high-voltage ceramic capacitors are different. High-voltage ceramic capacitors are generally designed for 20 years of use, and are generally guaranteed for at least 10 years.

From the internal resistance of the two capacitors, the internal resistance of the high-voltage ceramic capacitor is smaller, which is determined by the respective structural characteristics. The internal resistance of the high-voltage ceramic capacitor is small, and the film capacitor is wound by the winding method, which causes the internal resistance to be large. Another negative effect of this large internal resistance is that the internal resistance of the capacitor will continue to increase during repeated charge and discharge, and the capacitor will be disabled in the circuit at a certain time.

Different capacitors are manufactured in different ways and lifespan. Both ceramic capacitors and film capacitors have an indelible contribution to the development of technology. Knowing it before use will help us!
